Schwalbe Magic Mary: The most successful of all Schwalbe's gravity tires, the Magic Mary's uncanny ability to find traction in both sloppy wet and powdery dry conditions made it the most blacked out tire in the history of EWS and gravity racing. Most riders choose the Supergravity (orange stripe), or the DH model (purple stripe). Magic Marys work well on both ends, but most rely on her massive grip up front.
